- After trace, This section seems belong the tegra194-spmic-p3668.dtsi for Xavier NX, Am I right?
- This photo is the part content of the tegra194-spmic-p3668.dtsi.
Is the yellow section indicates our Xavier NX is disable the Battery Charging already?? or I need to remove the whole section of backup-battery??
